We have that 3 * f(x) + 4 * g(x) = h(x) where f(x), g(x), and h(x) are all polynomials in x. If the degree of f(x) is 8 and the degree of h(x) is 9, then what is the minimum possible degree of g(x)?
Answers
9514 1404 393
Answer:
9
Step-by-step explanation:
Adding polynomials causes like terms to be combined. The sum cannot have a degree higher than the degree of any of the terms in the sum. If the degree of f(x) is 8, then the degree of g(x) must be 9 in order for the sum to be of degree 9.

Jack needs 22 pirates for every 2 pirate ships he manages.
Answers
Answer:
55, 121
Step-by-step explanation:
2*2 =4
22*2=44
but 4 is not the number we need and 4 is one less so we divide 22 by 2 and get 11 so 44+11=55
thats the first box.
The second box is 55*2+11 which is 121
55:is the first box
121 is the second empty box
And
122 pirates for 11 ships
22 pirates for every two ships that would be 11 pirates for every 1 ship so your basically adding 11 to every ship there
The ratio would be 11:1

A jewelry maker is designing a crown. The crown must have at least 45 gems, using only emeralds, rubies, and diamonds. The number of rubies must be 1 less than 3 times the number of emeralds. The number of diamonds must be 4 less than the number of rubies. Which inequality could the jewelry maker use to find the fewest number of emeralds, x, that can be placed on the crown?
Answers
Answer:
Step-by-step explanation:
X is the variable and x means multiplication symbol.
X + (X x 3 - 1) + (X x 3 - 1) - 4) ≥ 45 is the answer I got.
The answer to that inequality would be
X ≥ 7 I think

Answers
Answers:
1)10.80/12 =0.90
0.90+0.75=1.65
2)252/7=36 units
3)cost price = $9.25*225
= $2081.25
Selling price = $15.75*225
= $3543.75
Profit = Selling price - cost price
Profit = $3543.75 - $2081.25
=$1462.50
5) FV = L*(1 + rt),
Where FV is the amount to repay; L is the borrowed amount (the loan amount) and "r" is the annual interest as decimal; t is the time.
In your case L = 2400 dollars; r = 8% = 0.08 (as decimal) and t = 0.5 of a year (6 months).
Therefore,
FV = 2400*(1 + 0.08*0.5) = 2496.
In 6 months, Della Rilley must repay $2496

Explain step by step how to do 10.25 x .15.
Answers
Answer:
1.5375
Step-by-step explanation:
Multiply without the decimal points, then put the decimal point in the final answer
1025 x 15 = 15375
....
10.25 has TWO decimal places
0.15 has TWO decimal places
Therefore, when you multiply with the decimal points (10.25 x 0.15), the answer should have FOUR total decimal places.
So the answer is 1.5375

Step-by-step explanation:
First you substitute the x's: 2(3y-1)-5y=8
Then you open parenthesis:6y-2-5y=8
Combine like terms: y-2=8
Bring the 2 to the other side: y=10

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!
Answers
Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
